Just in case anyone was wondering, I decided to play around with some proportions.
Using the 3286 ship as a reference, and basing the size off the playmobil cannons, were Playmobil to release a grand flag ship ala HMS Victory, brandishing 100 guns across 3 gundecks (not including the main deck), AND have a proportionate bottom hull to accommodate a realistic waterline, according to my calculations, in Playmobil proportions, the HMS Playmobil Flagship would be about 1.8 metres long (1.3 metres without the bowsprit) and 1.8 metres tall to the highest mast.
This is about a ratio of 3:1 (as far as length goes) when compared to the existing 3286 ship that is only about 60 cm long, and about the same in heighth. (technically though, this imperial ship is 9 times bigger than the 3286; it would literally take 9 3286 ships to hack up and join together to make this ship with 3 gundecks totalling 100 guns. Just in relative cost alone, considering a brand new 3286 at original retail went for about US$80-90, that would bring this size ship to about US$720 at LEAST!)
My measurements may be a little off, but the point is, this thing would be about as tall if not TALLER than me! (I am 1.6 metres tall). Just to check, I did stack 3 3286 ships end to end and layed down next to them to find that their length did in fact exceed my own. From the pic you can see the 100-gun warship in playmobil proportions is roughly 3 times as long as the 3286 ship, just to accommodate about 15-16 guns per row (one 3286 can theoretically accommodate about 5 guns across the length of its hull, although Playmobil only gave us 4 ports).
Take a look at this behemoth monstrosity!
Bigger, even, I wager, than MacGuyver's Dolphin. Hmmm, after looking at how unrealistically huge this would have to be, I am beginning to think MacGayver's Dolphin is the closest we may ever see to a Playmobil multi-decked flagship. This just seems too big for a company to produce realistically.
I still think it may have SOME hope if it can be built through a series of expansion components. I think, realistically, perhaps a mere extended hull with a third mast ala MacGuyver's Unicorn may be the best we can hope for from Playmobil, without having to customize one ourselves.
